Germany, Munich: Siemens launches two new Sentron 3WA Power Circuit Breakers.
Siemens has launched two new additional versions of Sentron 3WA Power Circuit Breakers, also known as air circuit breakers (ACBs).
Siemens said that Series 3WA3 meets the requirements of UL1066 and IEC60947-2 standards, which enables customers to use it worldwide. This is particularly advantageous for switchgear manufacturers and OEMs producing systems for both standardization areas – IEC and UL.
The 3WA2 series is designed exclusively for the UL489 market. The two new ACB model series complement the 3WA1 version for IEC markets.
The Sentron 3WA ACB UL series 3WA2 and 3WA3 are available in three frame sizes with rated current ranges from 800 to 5,000 A.
As a core element of low-voltage switchboards, ACBs reliably protect electrical installations in buildings, infrastructure and industrial facilities from damage caused by short circuits, ground faults or overload faults. This is essential also for critical infrastructure, such as hospitals or data centers.
The Sentron 3WA circuit breakers are built to perform over the lifetime of a facility. They support software-based planning and engineering, and digital testing and monitoring.
“Our highly flexible ACB series perfectly addresses the needs of switchgear manufacturers and panel builders in an environment characterized by increasing complexity, digitalization, and cost pressures,” said Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure.
The Sentron 3WA ACB trip units also have standard features, such as the integrated arc energy reduction feature (Dynamic Arc Flash Sentry, DAS+), which ensures that Sentron3WA ACBs trip more rapidly in the event of a fault during work being carried out in the immediate vicinity of live parts. In this way, the arc energy and thus the energy released in the power distribution equipment room is reduced. This technology complies with the National Electric Code (NEC) for the US market; it is designed to protect service technicians from serious injury resulting from arc flash hazards.
